ROLLER BEARING. i

Application led June 16,

To all whom t 'may concern.'

Be it known that I, LnoNAnn S. ALDRIDGE, a citizen of the United States,and a resident of Chazy, in the county of Clinton and State of New York,have invented a new and Improved Roller Bearing, of which the followingis a full, clear, and exact descrip- This invention relates toimprovements in roller bearings, an object of the invention being toprovide a roller bearing for wheel axles, in which a minimum number ofparts are utilized t0 obtain a maximum of eflif ciency.

To be more specific, one object of the invention is to provide a rollerhearing in which the rollers are carried by a cage and provides meansfor locking the cage within the axle box-or sleeve, so that there is nodanger of losing the' roller bearings when the wheel is removed fromrtheaxle.

Anotherobject is to provide a bearing which will be sim-ple andpractical in construction, strong and durable in use, which will needvery little attention.I and which will be comparatively inexpensive tomanufacture. I

lVith these and other objects in View, the invention consists in certainnovel features of construction and combinations and arrangements ofparts, as will he more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings Figure 1 is a view mainly in longitudinalsection through a Wheel axle with parts broken away for clearness;

Figure 2. is a view in side elevation of the bearing cage;

Figure 3 is a View in section on the line 3 3 of Figure 2, the dottedlines indicating the axle sleeve; Figure 4 is a similar view on the line4.-4 of Figure 2; and

Figure 5 is a plan view of the locking sleeve 17.

Referring in detail to the drawings, 5 represents an axle formed withthe 'usual spindle 6. The spindle is screw threaded adjacent its outerend, as' indicated at 7. A shoulder 8 around the inner end of thespindle is providedl with a. dust groove 9.

The axle sleeve or box 10 is provided at its inner end with aninternally enlarged bore formng a shoulder11. The outer end of the axlesleeve` is formed with an annular 1921. Serial No. 477,992.

and is locked in place by a threaded gasket l5 which fits a threadedportion 16 of theA sleeve-1() located between the shoulder `11%-- of thesleeve and the shoulder 8 of the spindle. rlhe gasket ltr securely locksthe cage 13 within'the sleeveu 1() so that the cage will not fall out ofthe sleevewhen the wheel is removed from the spindle.

The sleeve is locked on the axle by a locking ,sleeve 1T fitting overthe outer end of the spindle (l and held against movement by a lock nut1H screwed on to the threaded outer end of the spindle. A set screw 19carried by the nut 1S is selectively engageahle in any one of a seriesof pockets 207i formed in the bottom of the cup-shaped sleeve 17.

The invention in this case resides partially in the particularconstruction of the bearing cage 13. Referring in detail to Figures 2,5l and 4. it will be noted that the cage which is substantiallycylindricalA in shape, includes end rings 21 connected by a plurality ofparallel longitudinal bars 22. rhljacent their ends, the adjacent faces23 of the bars are located in a radial plane relative to the center ofthe cage. but adjacent the intermediate port-ion of the hars 22, the twoside walls of each bar are parallel, as indicated at 214( in Figures 2and el, to provide mounting for the intermediate portions of relativelylong' roller hearings 25. It will be seen that the bearings 25 aresupported upon the portions 24V of the. hars 22 and have no contact withthe ends of the cage. This peculiar mounting of the loearings permits a.slight rocking movement thereof and at the same time positively preventsthe hearings from falling through the cage when the wheel is removedfrom the axle.

It will be noted thatl provide a bearing surface which extends almostthe entire length of the spindle so that there is a minimum amount offriction between the spin- 1.
